Case studies by industry
At Premium PSU we have worked with projects from different types of sectors or industries. We highlight four main areas: Transport and Rail, High Tech, Energy and Extreme Environments.
What is an Electronic Fuse (eFuse) and Why Is It Replacing Conventional Fuses in Industrial Panels?
The electronic fuse (eFuse) detects overcurrents in microseconds, interrupts the circuit without blowing, and automatically resets. Unlike a conventional fuse, it indicates which channel has failed via an LED or digital signal, enables selective channel-by-channel protection, and eliminates the need for spare part stock.A solution that becomes more cost-effective than traditional fuses in installations with more than 3–4 faults per year, despite its higher unit cost.
